Oxygen is compressed from an initial state of p1 = 1 bar, T1 = 25◦ C to a final state of p2 = 650 kPa, T2 = 270◦C in a compressor operating at steady state. Model the oxygen as a perfect gas with γ = 1.4 and cp = 0.92 kJ/kg·K. Neglecting stray heat transfer and kinetic and potential energy effects, determine: (a) the work, in kJ per kg of oxygen flowing through the compressor. (b) the isentropic efficiency η for the compressor.

Two flowing streams of argon gas are adiabatically mixed to form a single flow/stream. one stream is 1.5 kg/s at 400 kpa and 200 c while the second stream is 2kg/s at 500 kpa and 100 ? . it is stated that the exit state of the mixed single flow of argon gas is 150 c and 300 kpa. assuming there is no work output or input during the mixing process, does this process violate either the first or the second law or both? explain and state all your assumptions.

Refrigerant-134a enters the compressor of a refrigerator as superheated vapor at 0.14 mpa and -10°c at a rate of 0.05 ka/s and leaves at 0.8 mpa and 50°c. the refrigerant is cooied in the condenser to 0.72 mpa and 26'c. it is then throttled to 0.15 mpa. sketch the t-s diagram for the system and evaluate: 6) the rate of heat removai from the refrigerated space (kw), it) the power input to the compressor (kw), ii) the isentropic efficiency of the compressor (%), and iv) the cop of the refrigerator.
